Sorcerer Decoding Software

Whilst looking for digital decoders I read a review on the software package Sorcerer. The software can be used with any HF receiver and allow you to decode a multitude of digital modes. You will find the standard FAX, CW, PSK and olivia decoders, but also the Nato standard Stanag.

Whilst testing the software I centered the receiver on 127.5 Khz and decoded the European EFR data signal. The European EFR system is described on their website, and uses 3 x 100 KW transmitters at Mainflingen 129.1 Khz, Burg 139 Khz and Lakihegy 135.6 Khz. Your dial frequency may vary a little depending on the location of the signals in your passband.

The EFR signal sounds like this.

You can download the free software. To decode EFR, run the program and select “Add Decoder” select EFR.

A setup guide is provided by the UXDF group.

Once received the decoded signal and  Sorcerer software should look like this.

The development of Demand Side Management (DSM) and the history of Radio Ripple control and load management is also explained here.

The decoded text shows the time, date and hex address, and the message is transmitted every 10 seconds. The system is described in some detail in this PDF file.

The system can be used to remote control street lights and power load management.

The decoding software Sorcerer would seem to have been developed by Avonlea Services, although the web provides no trace of this company today.

I cant find any trace of the described website in the help file and therefore cant credit anyone with the software. I have hosted the software for free download on my site, although if you are the author please get in touch.

The software is capable of decoding many modes including

The Birth of a New Digital Mode SIM31

Read the article on how the mode invented by Nizar Ben Rejeb was developed, and the advantages it has over traditional PSK31.

The article is available to read online.

You can download a free copy of the program, and read more online at ON4NB website.

A handy guide to installation can be read here.

Ive been using it for a few days now, but its too early to test its robustness. Many digital modes come and go over the years, but its always interested to test and understand the advantages and disadvantages.  It certainly looks very much like PSK31, but the program helps identify that by a CW ident SIM and in PSK31 you will decode NEW SIM31 on your screen.

It also has an interesting “beacon mode” that can fully automate QSO. Imagine the joy of leaving that on overnight, and in the morning finding out you have worked 10 new DXCC while you have been tucked up in tog heaven dreaming of that 30 meter tower and 5E stepper IR …
